PLLs (phase-locked loops) are common analogcircuits in SOCs (systems on chips). Almost allSOCs with a clock rate greater than 30 MHzuse a PLL for frequency synthesis. However, a“one-size-fits-all” PLL ...

A phase-locked loop (PLL) is a feedback system that combines a voltage-controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or ...

The Agilent RFDE and ADS tools provide today's engineer with an accurate, well-defined methodology for predicting first-order phase noise performance of the PLL in the above example. The ...

Clock signals provide reference timing to every integrated circuit and electrical system. Consumer applications typically use simple quartz crystals for reference clock generation. Other applications, ...
